Recent work has established that when transmitter Alice wishes to communicate reliably to
recipient Bob without detection by warden Willie, with additive white Gaussian noise …

Owing to the ever increasing of information privacy requirement, covert communication has
gained more and more attention, whose effective range is limited by the trade-off between …

Alice may wish to reliably send a message to Bob over a binary symmetric channel (BSC)
while ensuring that her transmission is deniable from an eavesdropper Willie. That is, if …

Covert communication conceals the transmission of the message from an attentive
adversary. Recent work on the limits of covert communication in additive white Gaussian …

Physical layer covert communication is a crucial secure communication technology that
enables a transmitter to convey information covertly to a recipient without being detected by …

Internet of Things (IoT) systems are of paramount importance to provide ubiquitous wireless
connectivity for smart cities. However, such systems are facing security challenges due to …

The laws of quantum physics endow superior performance and security for information
processing: quantum sensing harnesses nonclassical resources to enable measurement …

The recent square root law (SRL) for covert communication demonstrates that Alice can
reliably transmit O (√ n) bits to Bob in n uses of an additive white Gaussian noise (AWGN) …

We consider a communication scenario, in which an intruder tries to determine the
modulation scheme of the intercepted signal. Our aim is to minimize the accuracy of the …

In this paper, we study a covert Internet of Things (IoT) system. Compared with conventional
IoT systems that apply cryptography and information-theoretic secrecy approaches to secure …
